In this paper, we propose a super-resolution spectral estimation technique to quantify microvascular hemodynamics using optical microangiography (OMAG) based on optical coherence tomography (OCT). The proposed OMAG technique uses both amplitude and phase information of the OCT signals which makes it sensitive to the axial and transverse flows. The scanning protocol for the proposed method is id...

Our aim was to evaluate the effect of arthroscopic lysis and lavage of the temporomandibular joint (TMJ) on synovial microvascularisation by comparing preoperative and postoperative grades measured by power Doppler ultrasonography (US). We studied 22 patients with hypomobility, clicking, and pain in the TMJ. Power Doppler US were obtained preoperatively to assess the presence of synovial microv...

The success of human and embryo implantation depends on maternal and embryonic factors and their interactions. To asses uterine receptivity one must take various factors into account. Current advances in transvaginal 3D ultrasonography have allowed us to examine in detail and visualize pelvic organ structures to analyse their volumes with great accuracy (Alcazar et al., 2006 ),(Raga et al., 199...

conclusion following splenectomy, thrombocytosis can predispose the patients to an increase in cerebral blood velocities more than respected with anemia. but by transcranial doppler ultrasonography no evidence of significant stenosis were found in intracerebral arteries to conclude that the beta-thalassemia major patients were more prone to the development of stroke secondary to this abnormalit...

conclusion our study revealed that the hypoplastic umbilical artery group’s non-dominant cia had higher ri values than the contralateral dominant cia. results eleven of the 165 patients (6.7%) demonstrated a hypoplastic umbilical artery. second-trimester us showed median dominant and non-dominant cia pi values of 1.43 and 1.60 (p = 0.062), respectively, and median dominant and non-dominant cia ...
